Body Tag Assembly Date

Short answer: The body build-date code lives on the Fisher Body trim tag (firewall) and the Protect-O-Plate — it’s unique to the body shell and doesn’t appear on the Billing History. The body build date was generally about a week before the Billing History invoice date: the tag date is when Fisher Body sequenced the shell for build; the invoice date is when it cleared Final Assembly and certification just before shipping.

Reproduction Fisher Body trim tags are available. If your tag is missing, the Generation-1 Registry can estimate a close build date from VINs near yours. The Fisher Body Unit Number itself wasn’t random — it was generated by Sequencing (Broadcast) from the order’s colors/models/options/special orders, and cars weren’t necessarily built in the order received. No factory documentation of the exact numbering scheme is known to survive.
